FS#253 - Switch GUI: Intelligent automatic choice

If only 2 GUIs are available, skip the user selection and switch right into the only other GUI. What else would the user want?! Right!
If more than 2, already set the focus in the GUI list to the next possible item.

In Pandora OS 1.6 this feature is not yet implemented, but a somehow related feature has been added, which is worth mentioning:
As a default startup GUI, you can now choose "GUISwitch - Select your GUI on bootup".
